Unroll crescent roll pastry and pinch seams together to make a large sheet.
Mix together butter, brown sugar, cinnamon and salt. Spread cinnamon sugar mixture over dough and dot with raisins.
Roll up pastry into a log and slice into 12 pieces. Place each piece upright in a muffin tin.
Bake for 8 - 10 minutes until golden. Allow to cool for a few minutes while you mix up the icing. In a small bowl combine icing sugar with milk until a thick consistency, add more milk if needed. Pour icing over mini cinnamon rolls and serve warm.
